Continuous precipitation and heavy rain are important factors for the formation of debris flow.So effective monitoring of heavy rainfall and continuous rainfall is the important engineering measures to prevent debris flow disaster.Then a rain sensor is your best choice.


The principle of rainfall measurement

The rainfall sensor uses the principle of piezoelectric induction, consisting of a stainless steel cover that senses rainfall and a piezoelectric sensor on the bottom of the cover. The size and number of raindrops is proportional to the signal, so it can be converted into rainfall, not the vibration generated by raindrops, but filtered by a filter.



Main applications:

The rainfall sensor adopts piezoelectric rain gauge, with stable performance and high accuracy. It is widely used in high-speed railway and high voltage transmission lines, and the customer is highly recognized.
